Values
Note:
Changing Response Rate resets the following parameters: LOE Timer,
Fill Rate, Empty Rate, and Echo Lock.
Use a setting just faster than the maximum filling or emptying rate (whichever is
greater). Slower settings provide higher accuracy: faster settings allow for more
level fluctuation.
2.2.3. Echo Lock
Note:
Ensure the agitator is always running while SITRANS LR 200 is
monitoring the vessel, to avoid stationary blade detection.
Selects the measurement verification process.

If a material agitator or mixer is used in the monitored vessel, Echo Lock should
